Lepocreadiinae lepocreadiids (Digenea) from tetraodontiform fishes in the waters off Tasmania, Queensland and Moorea, French Polynesia

Two new species of Pseudocreadium are described from off northern Tasmania, P maturini sp. nov. from Meuschenia freycineti and P aubreyi sp. nov. from Acanthaluteres vittiger. They differ from the only other recognised species in the genus by the number of ovarian lobes and by size, and they differ from each other by size, shape, caecal length, forebody length, pre-oral lobe size, uterine position, excretory vesicle length and oral sucker shape. Lobatocreadium exiguum is redescribed from Sufflamen bursa, off Moorea, French Polynesia and Abalistes stellatus, Swain Reefs, Great Barrier Reef, Queensland. Records and measurements are given for Hypocreadium cavum from Sufflamen fraenatus and Lepotrema clavatum from Melichthys vidua, both off Heron Island, Great Barrier Reef, Queensland.

Up close and personal on physical education teachers' identity: Is conflict an issue?

Much of the research on teachers' work is informed by role theory, that assumes teachers' identity is largely ascribed. When there are inconsistencies in teachers' and others' expectations for different occupational roles such as physical education teacher and sports coach, 'role conflict' is said to occur. This stud), sought to investigate if role conflict was a major concern for Australian physical education teacher/coaches. Findings, informed by case studies with five teacher/coaches, challenge the assumption that moving between professional responsibilities causes role conflict. Rather, in moving across contexts, the physical education teachers managed inconsistencies in ways that resulted in positive and rawarding work experiences.

Teacher Use of Learners' Native Language in the Foreign Language Classroom

This article reports on an exploratory study into the use of students' native language (NL) by teachers in the foreign language (FL) classroom. The project was undertaken by four teachers of beginner French at the University of Queensland. The teachers' aim was to investigate the use of NL in a context which actively promotes an immersion approach to FL teaching. The audio recordings of the teachers' speech were transcribed to provide data for estimating the amount of NL, and for analyzing the various instances of NL use. The study indicates that the activity type is a significant variable affecting NL amount. It also isolates two strategic uses of NL, translating FL words into NL, and contrasting NL and FL forms, both of which involve intrasentential code switching with NL words embedded in an FL sentence. The study suggests that these strategies may facilitate acquisition during immersion in FL, but experimental research is needed to test the hypothesis that translation and contrast facilitate learning of FL vocabulary and grammar.

Analysis of toxin profiles in three different fish species causing ciguatera fish poisoning in Guadeloupe, French West Indies

A grey snapper (Lutjanus griseus), a grouper (Serranidae) and a blackjack (Caranx lugubris) were implicated in three different ciguatera poisonings in Guadeloupe, French West Indies. A mouse bioassay indicated toxicity for each specimens: 0.5-1, greater than or equal to 1 and > 1 M Ug g(-1), respectively. After purification by gel filtration chromatography, the samples were analysed by high-performance liquid chromatography coupled to mass spectrometry (LC-MS). The toxin profiles differ from one fish to another. C-CTX-1 was detected at 0.24, 0.90 and 13.8 ng g(-1) flesh in the snapper, grouper and jack, respectively. It contributed only to part of the whole toxicity determined by the mouse bioassay. Other toxins identified were C-CTX-2 (a C-CTX-1 epimer), three additional isomers of C-CTX-1 or -2, and five ciguatoxin congeners (C-CTX-1127, C-CTX-1143 and its isomer C-CTX-1143a, and C-CTX-1157 and its isomer C-CTX-1157b). Putative hydroxy-polyether-like compounds were also detected in the flesh of the grouper with [M+ + H](+) ions at m/z 851.51, 857.50, 875.51, 875.49 and 895.54 Da. Some of these compounds have the same mass range as some known dinoflagellate toxins. In conclusion, this study confirms the usefulness of LC-MS analysis to determine the ciguatoxins levels and the toxin profile in fish flesh hazardous to humans.

Broadening conceptions of curriculum for young people: Reports from three student-teachers on exchange

Research reports prepared by three Australian preservice teachers--Paula Shaw, Chris Sharp and Scott McDonald--undertaking their teacher education practicum in Canada, form the basis of this paper. The reports provide critical insights into three aspects of education for young people in both Canada and Australia. They also provide critical insight into the ways in which a practicum research project, along with the opportunities afforded through an international experience, enabled the preservice teachers to broaden their understanding of the curriculum for young people, of issues relevant to the diverse needs of young people, and of themselves and their priorities as teachers. The preservice teachers investigated three topics: attempts to reduce homophobia in schools; the presence or absence of Aboriginal content in the school curricula in British Columbia and Queensland; and "schools-within-schools" as a means to meet the needs of diverse student populations. Linda Farr Darling from the University of British Columbia provides a response to the three reports.

Teachers and productive pedagogies: Contextualising, conceptualising, utilising

Improving students' outcomes from schooling requires schools to be learning organisations, where both students and teachers are engaged in learning. As such, knowledge and talk about pedagogy need to be at the core of the professional culture of schools. This article argues that this will require the valuing of teachers' work, that is, their pedagogical practices, to be a central focus of educational policy. Dangers are associated with this argument in terms of understating the impacts of poverty, lack of funding to disadvantaged schools and other social factors such as the pressures of globalisation upon students' educational opportunities. Hence, while acknowledging the importance of pedagogy to students' outcomes, the article contextualises the argument through a recognition of the policy and structural conditions that work against the valuing of teachers and their work. It then conceptualises how, within this context, a focus on pedagogies can make a difference to students' academic and social outcomes from schooling. This conceptualisation utilises the productive pedagogies model of classroom practice, developed in a large Australian study of school reform, as an example of the forms of pedagogical practices that support students' achievement of academic and social outcomes. It is argued that such pedagogical practices ought to be a concern of teachers, school administrators, education systems and local communities interested in schools as learning organisations.

Becoming a teacher: student teachers´ experiences and perceptions about teaching practice

In an attempt to build a more comprehensive and holistic understanding of the complexity, dynamics and idiosyncrasies involved in becoming a teacher, this study focussed on the experiences of 295 student teachers. Their feelings, cognitions and perceptions regarding teaching practice were analysed using the short version of the Inventory of Experiences and Perceptions of the Teaching Practice. Results emphasise some of the difficulties experienced during this period (e.g., stress, sense of weariness and ‘vulnerability’), as well the positive perceptions of these student teachers regarding their growing knowledge and skilfulness, as well as their sense of efficacy, flexibility and spontaneity in their performance and interactions. Their perception of their accomplishments in achieving reasonable levels of acceptance and recognition within the school community and their positive evaluation of the guidance and support provided by their supervisors are also emphasised. Differences were found – in terms of gender and graduate course background – in the way these student teachers experienced some aspects of teaching practice.

Políticas de intervenção prioritária em Portugal: novas políticas, novas práticas?

Em Portugal, no final da década de 90 do século XX, começaram a ser desenvolvidas estratégias de discriminação positiva visando garantir o cumprimento da escolaridade obrigatória e a luta contra a exclusão escolar e social, designadamente nas periferias das grandes cidades. É neste contexto que surgem as escolas e os Territórios Educativos de Intervenção Prioritária (TEIP) pelo Despacho nº147-B/ME/96, de 1 de Agosto de 1996. Este programa, inicialmente inspirado nas zonas de intervenção prioritárias francesas, visava a intervenção de vários parceiros locais (professores, alunos, pessoal não docente, associações de pais, autarquias locais, associações culturais e associações recreativas) na elaboração do Projeto Educativo. Com o XVII Governo Constitucional o programa foi redefinido passando a incluir novas vertentes: necessidade de existência de um projeto educativo próprio; consultadoria externa; avaliação periódica de resultados em diferentes domínios (taxas de insucesso e abandono escolar, assiduidade, comportamento, participação, inovações organizacionais, parcerias educativas estabelecidas no âmbito do Programa, etc.). Foi também alargado a todo o território nacional, envolvendo atualmente cento e cinco agrupamentos escolares. Com esta apresentação visamos analisar se as novas políticas e diretrizes, no domínio da educação prioritária, contribuíram para a emergência de novas estratégias pedagógicas, organizacionais e de envolvimento comunitário. Os elementos em que basearemos a nossa análise serão os seguintes: (i) relatório nacional do programa TEIP (2010-2011); (ii) relatórios do programa de avaliação externa das escolas; (iii) entrevistas realizadas aos atores locais, designadamente a coordenadores e consultores dos projetos TEIP. As conclusões da nossa comunicação centrar-se-ão no papel dos atores locais no desenvolvimento do Programa TEIP e no impacto deste programa na melhoria dos resultados académicos, na diminuição da indisciplina e violência escolar e na construção de percursos de vida que contrariem as tendências para a exclusão escolar e social.

Public school teachers’ perceptions about mental health

OBJECTIVE To examine public school teachers’ perceptions about general health and mental health, and the way in which they obtained this information. METHODS Qualitative research was conducted with 31 primary and secondary school teachers at a state school in the municipality of Sao Paulo, SP, Southeastern Brazil, in 2010. The teachers responded to a questionnaire containing open-ended questions about mental health and general health. The following aspects were evaluated: Teachers’ understanding of the terms “health and “mental health,” the relevance of the need for information on the subject, the method preferred for obtaining information, their experience with different media regarding such matters, and perceptions about the extent to which this available information is sufficient to support their practice. The data were processed using the Qualiquantisoft software and analyzed according to the Discourse of the Collective Subject technique. RESULTS From the teachers’ perspective, general health is defined as the proper physiological functioning of the body and mental health is related to the balance between mind and body, as a requirement for happiness. Most of the teachers (80.6%) showed great interest in acquiring knowledge about mental health and receiving educational materials on the subject. For these teachers, the lack of information creates insecurity and complicates the management of everyday situations involving mental disorders. For 61.3% of the teachers, television is the medium that provides the most information on the topic. CONCLUSIONS The data indicate that there is little information available on mental health for teachers, showing that strategies need to be developed to promote mental health in schools.
